WARNINGS.

 Always keep a balanced stance. Do not stand 

on the log. Be alert to the fact that the log may roll over. 

When working on a slope, always stand on the uphill side 

of the log.

Bucking

Bucking is cutting a log into 

lengths for easier handling. 
To saw a log lying on the ground, 

first saw halfway, then roll the log 

over and cut from the opposite 

side. To saw the end of a log 

supported off the ground, first 

saw up from the bottom one-third through the log then finish 

by sawing down from the top. To saw a log in the middle of 

two supports holding it off the ground, first saw down from 

the top one-third through the log then finish by sawing up 

from the bottom.

CAUTION.

 Avoid cutting into the ground as this will very 

quickly dull the saw chain.

Pruning

Pruning is the removal of a limb 

or branch from a standing tree.

WARNINGS.

 Do not use an 

unstable foothold or ladder. Do 

not overreach. Do not saw above 

shoulder height. Always use both 

hands to hold the saw.
First cut up from the bottom and finish down from the top.

Maintenance 

NOTE.

 Before cleaning your chain saw or carrying out any 

maintenance procedure, make sure that the engine is off 

and is cool. Disconnect the spark plug to prevent  

accidental starting.

Maintenance to be preformed after each use

1. Loosen the top cover knob (12) and remove the top  

cover (11).

2. Remove the air filter (8).
3. Split the air filter into its two 

halves and clean the mesh. 

Dry particles can be removed 

by tapping on a hard surface. 

More stubborn dirt may 

require washing out the filter 

with petrol or using an air 

compressor.

4. Re-assemble the two halves 

and replace the airfilter, top  

cover (11) and knob (12).

5. Take off the guide bar (1)  

and maintain it as follows, 

remove any sawdust from the 

groove in the guide bar.

6. Make sure that the oil port is 

not clogged. Grease the nose 

sprocket at the tip of the  

guide bar.

7. Check for fuel and oil leakage 

and loose fastenings, 

especially those securing the 

handles and the guide bar. If 

any defects are found, take 

the tool to an authorised  

repair centre.

8. Clean any dust away from the cooling vents as clogged 

vents can cause overheating.
